LLM推理是指运行已训练好的AI模型以生成响应的过程，它是用户的主要成本来源，而非模型训练。这个过程涉及几个步骤，首先将用户文本转换为数字标记（tokens），然后与其他请求批量处理以提高效率。推理过程有两个阶段：预填充（prefill），模型处理整个提示词；解码（decoding），模型逐个标记生成输出。了解这些步骤有助于用户管理成本，因为API提供商通常按标记计费，并可能为非紧急任务提供折扣。 AI

影响了解LLM推理成本有助于用户优化API使用并管理AI应用的支出。

本文如何被排名

Signal score: 11 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Commentary; 解释性文章，详细介绍了LLM推理的技术过程和成本影响。
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: infra; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: High; Clearly on-topic for AI-industry coverage.
Story freshness: Breaking (< 6h); Fresh story with cross-source coverage still developing. Ranking may shift as more sources report.
